26 Claims.

The present invention relates to filling motions for shuttleless looms, and more specifically, to lling motions of a type adapted to control yarn fed from an external source to be taken by filling inserting devices such as are employed with looms of the type to which reference is made.

It is a general object of the invention to devise a filling motion which shall comprise a compact and unitary subassembly, and which shall function effectively to feed filling from an external source of supply to rapidly operated filling inserting devices functioning to insert filling in pairs of connected picks, each pick of whic-h is held in a separate shed.

A more specinc object of the invention is that of providing a filling handling mechanism driven in synchronism with other parts of the loom and which is especially designed to present the filling to an inserting means in a reversed relationship at alternating picks thereby to assure that each pick is inserted in as nearly as is possible the same general manner and under the same physical conditions and influences.

Itis another object of the invention to provide a filling motion as just above described which f' shall control the relationship of the filling at succeeding picks so as to maintain the loose or released end of the iilling at the same side, preferably beneath, the inserting means at each pick.

Another object of the invention is that of providing a filling cutting and clamping means adapted to function beneath and very close to the inserting means and which is operated in a very simple and effective manner for exploring and engaging the filling for withdrawing it out of the range of inserting means and for severing and releasing one end while clamping and retaining the other cut end.

It is a further object of the invention to provide a filling manipulating injector adapted normally to maintain the filling out of the path of the inserting means, but to present it in the path of that means at appropriate times, and in combination therewith, a thread return .guide adapted to cooperate with the injecting device for confining the filling in such manner that it is always properly engaged at appropriate times as the injecting means functions, and also, for releasing or freeing the filling from the injecting means at proper intervals during the filling inserting cycle.

Other objects will be apparent from the following more detailed disclosure.

In shuttleless looms and especially in looms of that type in which filling is taken from an eX- d ternal sour-ce of supply and is inserted in a warp shed by rapidly reciprocating devices of a type Well known in the prior art, it is essential that the filling be handled or guided in such manner as to present it at appropriate times and in a particular relationship so that it may be faithfully and correctly engaged by the inserting means. It is also necessary to release a free end of that filling at a time when an amount thereof has been drawn suiiicient for reaching across the entire extent of the warp shed and slightly beyond, and also to clamp or bind the filling so that no further quantity thereof shall be drawn from the source of supply until another pick is to be inserted. One very common form of weaving on these looms involves the insertion of a pick from one side of the loom, then after changing the shed, insertion of a second pick from the same side maintaining continuity of filling between the two picks thereby to provide for a selvage at that side of the fabric. While it is quite possible to insert filling in these looms and from an external source of supply according to other methods, the description hereinafter to be given will refer particularly to insertion from a single side of the loom and to the production of fabric wherein the filling takes the form of repeated pairs of connected picks or hairpins" as just described.

Duplication of the mechanism at each side of the loom makes it quite possible to insert filling from both sides and to produce a selvage at each side, although that involves added mechanism. The advantage of a selvage formed by the loops between adjacent connected picks is to be desired, but that is to an extent counteracted by other disadvantages with which we are not especially concerned at this point. It should sufnce to say that the invention may be practiced at a single side or at both sides and the mechanism, as will be well understood by those conversant with this art, merely involves duplication and in some instances, reversal of the shape of the parts and positioning thereof since the operation is to be performed at the opposite side and in a reverse direction. If the filling is inserted entirely from one side, a selvage may be produced at the opposite side by locking the projecting ends with twisted selvage threads, or in any other satisfactory Way.

The invention comprises a complete unit mounted adjacent the end of and at the front of a loom of the type described and which preferably is driven from some part of the loom which is moving synchronously with the filling inserting means, lay, and other parts. The device itself Fig.v 40 is a view showing av small section of fabric woven according to the method employed.

Now referring to Figs. 1, 2 and 3, the general organization of a shuttleless loom to which the invention has been applied will be described. The loom comprises, among other parts, loomsides 50 and 5|, a plurality of girts 52, and other structural parts including a breast beam 53 which go to make up a conventional loom framework. The warp threads are supported at the back of the frame and pass through the usual warp stop motion devices and are then threaded through heddles in heddle frames such as the frame 54 hung upon a top motion including the suspending straps 55, 56 passing over sheaves 51, 58 rotatable on brackets carried by an arch 59. Springs enclosed within a casing 60 bias the parts just described in such manner as to draw the heddle frames upwardly while cams at the lower part of the loom structure function upon treadles to pull downwardly upon other parts of the harness mechanism, only some of which show in Fig. 1, but which need not be described here since they are conventional and their actual construction and mode of operation are well understood by those skilled in this art.

The warp threads after passing through the heddles are threaded through a reed Bl carried between a lay beam 62 and a hand rail 63, Fig. 12, after which the warp passes to the fell of the fabric and the fabric then passes onwardly to the take-up mechanism such as the usual sand roll or other equivalent devices, and to a cloth roll upon which it is wound and by means of which it may be taken from the loom when a sufficient quantity of material has been nished. The mechanism incidental to take-up of the fabric and winding on the said roll is shown in part in Fig. 1, but need not be described in detail as it is not diiferent from that employed in conventional looms.

As illustrated in detail in Fig. 12, and as shown to some extent in Fig. l., the lay beam 52 is carried adjacent the upper ends of swords 64, extensions of those swords in an upward direction being employed for fixing the hand rail in position. The swords attach in an adjustable fashion at their lower ends to brackets or levers 55 which are pivoted on a rock shaft 65. By means of cams 51 and 68 rotatable with a cam shaft 59, the lay mechanism is swung to and fro in properly timed relationship. The cams 5l and B8 function upon followers l0 and 1I carried at the end of arms, one of which is integral with the bracket 55 and the other of which is pivoted thereto at 'i2 and pressed by means of a spring 'I3 in such direction that the followers always bear tightly against their cams. The cams themselves provide for a dwell period of 180, more or less, and that dwell period serves to hold the lay structure in stationary position while the filling is inserted. During the active part of the cycle the cams move the swords and lay structure forwardly tO effect beating up of the last laid pick of filling.

The lling is inserted by carrier devices mounted at the ends of flexible tapes, one at each end of the loom, and in Fig. 3, one such tape is illustrated at 14, it being understood that these tapes tend to maintain a rectilinear form, but are flexible enough to be wound upon the tape wheels 'l5 as they are withdrawn from the shed and outwardly beyond the filling motion. These tape wheels are of relatively light construction and are mounted on pivots 'i6 carried in supports at the outer portions extending frame structures which include the horizontally disposed members 11 and the more or less vertically disposed parts 13. This framework is attached to the loomsides and the entire structure ties together to make a relatively rigid supporting means for the tape Wheels which are oscillated to and fro under the influence of certain intermeshing gears, shafts and reciprocating racks, the latter being reciprocated by cranks or eccentrics, or in any other satisfactory manner all as described in United States Patent 2,604,123. The manner of reciprocating these tapes or of imparting movement to other similar filling inserting means which may form the basis of a loom structure to which the invention is applied differs according to the prior art, and it is not deemed necessary to go into detail concerning that part of the basic loom mechanism since the invention may be utilized to advantage with many looms of the same type,

The entire loom is driven by a .motor or from any other convenient source of power and that power is preferably conveyed through clutch means and the loom is to be started and stopped by engaging or disengaging the clutch, and preferably, at the same time, by releasing and applying a brake as is frequently done in looms of all types so as to effect stopping as rapidly as possible for reasons well known to those skilled in the art.

The tape wheels are preferably shielded by casings 'I9 in which are carried at angularly spaced points antifriction rollers for facilitating movement of the tape as it is wound upon the wheel 'l5 or unwound therefrom. The tape passes through straight guideways just prior to its entry into the shed within which it inserts filling.

The invention as herein illustrated is applied to a shuttleless loom wherein the filling is inserted at one side only. That may be altered so that iilling is inserted at each side in which event, the actual construction of the filling carriers at-v tached at the ends of the flexible tapes would vary. In the latter instance, such carriers might preferably take the form illustrated in the copending application above mentioned. Vfhere filling is inserted from one side only, one of the carriers as illustrated in 13 and also in the diagrammatic views, comprises a boxlike, sheet metal structure 8| tapering downwardly to merge smoothly into the tape 1li and being more or less pointed as at 82 for passing through the shed more smoothly. rihe opposite or front face of the carrier is similarly pointed and at the top and lower portions of the boxlike structure, notches 83 provide for receiving the lling and for maintaining it centrally of the carrier as the latter pushes the lling inwardly to a point somewhere near the center of the shed or of the fabric being woven. The action of the carrier in thus proiecting the filling inwardly to approximately the center of the shed is such that a doubled length of lling is pushed inwardly, one end of that nlling extending back to the supply and the other being held for a length of time until suicient material has been projected inwardh7 so that one end may be released or cut and thereafter no further filling drawn from the supply. One end of the said doubled length of filling extends from the top notch 83 while the other end will extend from the corresponding lower notch and along the bottom of the carrier and beneath a portion of the tape. The actual manner in which the tapes are disposed with respect to the lay and the manner in which the lling is controlled by accesso 7 the tapes to tensionit isA described in the patent abave-mentioned and neednot be described in greater detail here.

The .opposite carrier member comprises a hook and trap structure as illustrated in the diagrammatic figures and that hook and trap serve to .engage the filling at transfer and extend it over the rest. of the shed. It should sufiee tostate here that the ca-rrier at the left hand side of the Inachine according to the specific illustration here given engages that short stretch of filling between the top notch 83 and the notch directly below at the lower part ofl the carrier and hav-ing engaged it and .effected transfer from the carrier 8| to the opposite or hooked carrier 8d, Fig. 29, carried by a tape d5. corresponding to tape .14 the laction of the latter carrier simply results in drawing out the filling which yhas been measured off and inserted as a doubled length so that ,the released or cut end thereof is extended across the shed to the opposite side of the fabric and' for a very short. extent beyond for the purpose of effecting the formation of some type of selvage as above indicated.

The supply of filling is preferably mounted adjacent the lling motion itself, but may be carried at any convenient locality at that endof the machine. Here the filling in the form of supplies S is mounted upon spindles such as the spindle 86 carried at the upper end of bracket 8'.' fixed on a platform 88 mounted at the end of the loom framework as shown. The supplies are preferably arranged in duplicate with the trailing end of one being attached to the leading end of the other so that when the. first becomes exhausted, the loom may continue to draw filling from the other so that there Will never be a point at which the loom must stop due to exhaustion of filling.

The filling indicated by F is drawn axially from the package and passes through an aperture or eyelet 89 in a shield 90 which to some extent controls ballooning of the, filling and. Separates the supplies from the. lling motion, that shield 90 being removed in Fig. 3 so that parts which would otherwise be. hidden are exposed to View,

The filling motion itself, indicated generally by a numeral 9|, is to a great extent enclosed witl i in a casing 92 having a cover 93 which rocks about a hinge pin 94. ,so as to tip backV and expose those parts within the casing. This entire filling motion is devised as a unitary structure and is mounted upon a bracket 95 supported on the may chine framework and preferably adjustable there, on so as to position the unit by moving it through a limited extent. The interior of the casing as well as the actual parts which control the lling itself are collectively shown in Fig. 4. All of the instrumentalities are cam controlled, thesecams being supported upon a shaft 9.6, carried in bearings 91 and 98, herein shown as antifriction type bearings, although it is to be understood that other bearings may be employed if desired. 'I'he casing may be oil tight at its lower part, at least, and thus the internal parts lubricated by dipping in oil in a reservoir provided by the lower part of the casing, or each part may be separately or otherwise lubricated.

The shaft 9E as illustrated in Figs. 2 and 4, is driven through spiral gears 99 and |00, the former being fixed at the upper end of a more or less vertically disposed drive shaft Il. The gear |00 is fixed at the end of shaft 96 and both of these gears are enclosed within casing member |02 which is bolted to or otherwise attached to the side of the main casing 92.

The upper end of shaft l|10| iscarried in aloe/arng |03: bolted to the side `tif-casing 9.2 while the lower end of :that shaft is borne within a correspond-ing bearing |04. which forms a part of. a bracket l0 5- bolted tothe loomside 5.0 and adiut'- able thereon for positioning the parts and assuring proper intermeshing of the various gears.

Shaft |0 is driven from, the main cam 69 through gears H1B and |01, the latterbeing mountw ed upon a short spindle I 08 carried in, bearingsV |03 also. forming a parli of bracket .|05 and this gear |01 also drives a. bevel gear l I0 which in turn meshes with and drives a, .corresponding gear lli fixed at one .end of a shaft 12, the other endy of that shaft having keyed orotherwise xecl theretofa corresponding gear l I3 meshing with a. gear U4 at the lower end of shaftv |04. The shaft H2 is rotatable within .the bearings H5 and M5 depending' from the bracket E05, Thus, rotation. of cam shaft 6,9V as the loom is operated, through the. train of gears, inst dascribed, drives the cam shaft 9o within the casing or housing 92.. that shaft being driven at one-half the speed of cam shaft 69 so that each of the cams. carried by the shaft. 96- makes one complete revolution for every two picks inserted, that is,.1f.Qr eac-h .complete cycle of inserting a swcalled hairpin or pair of; connected picks. Y

The fol-lowing description devoted to the outer binder or clamp, the injecter, the filling return guide, and the inner clamp and cutter will be taken up in the order stated, each of the, said mechanisms being described in detailalong the details of that part of the operating mech-v anism which governs its movements.

The filling F after being drawn through the. eyeletsy 89 or corresponding guide means and after being drawn from the supply. may pass through tensioning means. (not shown), but which. may takel any convenient form desired, For example. disk tensions may be employed and, the tension to be imposed upon the lling by such devices may be adjusted in accordance with the material itself and with other factors. If desired, other devices adapted to prevent knotting or formation of slubs or collection of lint uponV the filling and possibly causing undesired effects may be employed if desired.

The outer clamp shown in Figs. 4, 5 andV 13 com,-

v -I prises a relatively fixed and a movable member,

the relatively fixed portion of the clamp being constituted as a pad lat the lower end of the depending arm I8, the latter being comprised as a part of a complete bracket I9 bolted or otherwise attached to an upper, attened portion of an extending hub or boss |20 formed as an in tegral or other part of the casing 92. So that the Afilling may be maintained in alignmentr with the center of the clamp a pair of guides |2| and |22 are adjustably attached by means of screws passing through slots and into a widened part of the bracket I9. Apertures in these guides permit the filling to pass between and more or less centrally of the fixed pad and the cooperating movable clamp member |23 which is formed at the end of a plunger or axially movable rod |24 guided within suitable bearings in the hub or boss |20. A spring |25 bearing against a shoulder on the plunger |24 and against a cooperating shoulder within the hub |20 is under sufficient compression for forcing the plunger and thus the movable portion of the clamp outwardly against the fixed pad ||1 with a force appropriate for maintaining the thread or filling in clamped eneasement in the event the clamping action is in effect, but permitting movement of the plunger |24 inwardly of the casing 92 at such times as a cam |26 carried by shaft 96 affects a follower |21 at the upper crooked end |28 of a two armed lever pivoted at |29, the lower end |30 of which is forked to engage a collar |3| at the inner end of the plunger.

The cam |26, as illustrated in Figs. 4, 5 and 20 and 21, is mounted upon a hub |32 which is pushed over a cylindrical portion and also against a conical portion of the shaft 96 and held in place by a nut |33. The cam is comprised of two portions, one disk portion which extends throughout 360 and a filler or adjustable part |34 which is Aattached to the disk by bolts |35 and |36 passing through an elongated slot and adjustable throughout an angular extent so as to vary the position of rise for the follower |21 or the time of releasing the filling by varying the relative angular position of the point of the cam |31. The clamp is closed as the follower |21 drops from the point |36. By loosening the nut |33, Fig. 4, and moving the entire cam |26 on the shaft, this point of drop-off is capable of being varied, thereby to time the termination of drawing filling from the supply, and therewith, the length of material going into the first pick. As the follower drops from the point |36, the spring |25 is permitted to close the clamp, and `when it rises upon point |31, the plunger is withdrawn against the tension of spring |25 and the cla-mp is opened. The clamp must be opened prior to the start of drawing lling from the supply for the second pick.

Now referring to Figs. 4, 6, 7 and 13 in particular, the injector the purpose of which is to posii tion the filling in front of or in the path of the carrier 8| will be described in detail. The injector itself comprises opposed arms |39 and |49, Fig. 4, which actually are formed as a U-shaped thread controlling `and guiding means pivoted to be turned about an axis along which it may also move axially. These arms |39 and |40 are adjustably positioned but xed to one end of the spindle |4| which is rotatable in bushings or other bearings in a hub or boss |42, Fig. '1, projecting *i from the casing 92, and Ialso in a bearing S43 intermediate the casing. The arm has an aperture |44, Fig. 13, through which the filling is threaded and the opposite arm |39 has two nibs and |46 which are formed with a slight incline at their inner surfaces so that the thread may slip therefrom when desired. These nibs may also be bent away from the center of the pivot as illustrated in Fig. 4.

The filling threaded through aperture |44 may 1 not escape therefrom, but it is only at such times as the filling injecting means is positioned parallelly with the direction of movement of the carrier that the nibs may engage at either side of that filling. After the lling has been thus trapped between the nibs |45 and |46 while the arms are horizontally disposed and with the aid of other mechanism hereinafter to be described, that filling is injected into the path of the carrier by pushing the injector arms toward the path of the carrier or away from the casing 92 toward the back of the loom. At the same time the injector is oscillated or rotated throughout about 90 from horizontal position to a more or less vertical position thereby to position the stretch of filling extending from the aperture |44 to one of the nibs |45 or |46 across the pathway of the carrier. As will hereinafter be described, the rotation throughout approximately 90 occurs first in one direction for one pick and then in the li)Y other direction for the next succeeding pick for a purpose hereinafter more definitely explained.

The mechanism for moving the injector toward the path of the carrier 8| will first be described. The central orv largest portion of shaft 96 has keyed thereto a hub Uil1 to which are attached cams |48 and |49. These cams shown more clearly in Figs. '7, 22 and 23, are complementary and may be adjusted as a unit about the shaft, but are locked thereto when the proper position has been once determined.

These cams function upon followers |50 and |5|. The followers |50 and |5| are positioned in offset relationship, one to one side and the other to the other side, of the two armed lever pivoted at |29 having an upwardly directed arm |52 and a depending arm |53 the lower end of which is forked at |54 to engage between collars |55 xed on shaft or spindle |4| and thus, by rotating thesel cams'as the shaft 96 rotated, the arm 53 is rocked to and fro in properly timed relationship to project the injector inwardly and to withdraw it in properly timed relationship to the movements of the filling carrier 8|.

The rocking or oscillating movement imparted to the injector is derived from the complementary cams |56 and |51 which are also mounted for rotation with the shaft 96, these cams being bolted to the hub |58 which is in turn keyed to the shaft as illustrated in Fig. 4 and acts to impart movement to a bell crank lever having arms |59 and |60, as seen in Fig. 6, and a hub portion pivoted on a stub shaft |6| bolted to the side of the casing 92. Followers |62 and |63 mounted for rotation upon opposite sides of the general center line of the lever impart movement from the cams |56 and |51 to the bell crank lever, the swinging movements of that lever being carried through to rock a cross shaft |64 mounted in bearings |65 and |66, Fig. 4, cast integrally or otherwise formed as a part of the casing 92.

A pinion |61, Fig. 6, is keyed or otherwise fixed to the shaft |64 between the two bearings just above mentioned. The arm |66 of the bell crank lever is formed at its free end as illustrated in Fig. 6 to provide a sector |68 having teeth cut therein for meshing with the pinion |61. Thus, rocking movement of the bell crank lever causes a rotation of the shaft |64 first in one direction and then the other and the ratio of the effective moment arms of these parts and the amount of angular movement imparted to the bell crank lever causes approximately a rotation of this shaft at each oscillation thereof.

YNow referring to Fig. 4 and also to Fig. '1, the spindle |4| to which the injector is attached through the coupling hub |69 is adapted to be turned on its axis independently of its movement along or axial of that axis by a bevel gear |10 which is splined internally to engage corresponding splines |1| at that end of the spindle. The hub |12 of the gear is spaced from the intermediate bearing |43 by a washer |13 and from an opposed guide and thrust member |14 by a sleeve |15. An extension |16 of reduced diameter is guided within a bushing |11 carried within the guide and thrust member |14 which extends outwardly of the casing 92 being bolted thereto in any suitable manner and having a part |18 extending far enough to permit the extreme axial movement of the reduced end |16 of the spindle.

A corresponding gear |19 is keyed to the adjacent end of shaft |64 and meshes with gear |19 so that the rocking movement imparted to the cross shaft is conveyed to the spindle |4 through ll the splines which interconnect the hub of the gear and that spindle.

Again referring to Figs. 6, 24 and 25, the complementary cams |56 and |51 are adjustable as a unit upon the shaft and are provided with double the number of lobes to be found on the cams |48 and |49 since at each time the injector is moved to present the filling to the carrier 8|, it must be rocked first in a counterclockwise direction for pick #l of a connected pair of picks of lling and then returned, and for pick #2 of the pair, must be rocked in the opposite direction and returned while, of course, the axial movement is merely duplicated on that second pick.

Now referring to Figs. 4, 8, 9, 10, 11, 11a and 16, the inner clamp and cutter will be described. That thread manipulating and controlling instru mentality includes a relatively fixed clamp element |80 which has a leather or fibre facing l8| and which is disposed at the end .of a plunger |82 which extends back to a boss or support |83 cast integrally or otherwise formed as a part of the casing 92. While this part of the clamp is referred to as the relatively stationary clamp member, it is to be understood that it has a slight resiliently opposed movement back into the support |83 and the term applied to it is used merely by way of distinguishing between it and the other portion of the clamp and of the cutter which is actually moved positively by mechanism hereinafter .to be described throughout a considerable extent for the purpose of .effecting the release, clamping and cutting Aof the filling. The movement of `clamp |80 and plunger |82 to which it is attached is for the purpose of providing a, resilient pressure between .the pad 18| ,and the complementary clamping surface of the movable clamp |84 which is shown opened in Fig. 9 and closed at Fig. 10.

Plunger .I 82,.as shown in Fig. 4;, moves backinto the support |83 againsta spring |85 and the tension on this latter spring is just sufficient to press the pad 18| against the surface Vof movable plunger lelement; |84 with the required amount of force necessary for holding the thread. A forked extension comprising the arms `|86 Aand I 8.1 engagea-ble at eitherside of a short projection .|88 having .a iiattened Aportion |89 .shouldered .at either `end prevents rotation of ythe .clamp and also limits movements thereof outwardly .under f' the influence of the spring |85. It is to be noted that Vas :illustrated in Figs. .4 and l0, .engagement of the movable clamp with .the pad [8| vmerely results in compressing spring .18,5 very .slightly and the arms |86 .and |81 actually move very little at that time, the movement being -just .sufcient to insure AContact .without controlling the movement of the clamp member |84 .with extreme precision and prevents 'any possible release of .the filling due to vibration .or the like.v

The movable clamp 'member |84 is Aattached at the end of -a cutter vbar |190 which .slides in the support |83 and -is so formed .at .its lower side as Vto provide .a cutter orshear member |91 which is hooked Yor inclined in suchdirection as to catch .the filling and to 'draw it .back during the lreturn movement of 'the -cutter .and clamp to sever or shear itagainst the sharp edge of la. spring'blade fl 92 better illustrated in Fig.-11. The end or `nose portion ofthe clampiandlcutter Just described .is bevelled at the vlower Isurface `and is pointed as at |93 for the purposeof slippingover the filling at the `time the cutter functions to engage and sever and rclamp it, :thereby serving to engage aboveiit and `to cam it yd owlowardly during an exploring stroke t0 the PQSQII H1113* trated in Fig. 16. It is to he undelStOd that ,ai that time the cutter moves outwardly beneath the tape 14 there being a very slight clearance between the top surface o f the cutter bar and the lower surface of the tape. The filling is then more or less underneath the tape or just to one side thereof and is separated from the tape as it angles downwardly from the carrier at the end of the tape so that there is always ample room for the point of the cutter to engage be, tween the tape and the filling. Continued movement of the cutter to the positions of Figs. 9 and. 16 engages the shear |8| over the filling so .that return movement thereof to the position of 10 must cut the filling and also clamp it between the members |8| and |84. The shearing action actually takes place a brief interval before clamping according to the preferred .timing as is customary in instruments of this sort.

As shown in Figs. 9, 10 and ll, a curved exten sion |94 notched as at |95 vfor reception of the filling tends to maintain that iilling in proper position with respect .to the cutter element v19| and is positioned slightly nearer the casing 92 than the point les of the cutter member .so as to keep the filling away from the blade 9| until contact is actually made with the. spring .blade |92. This added part may be used although itis no t necessary with some Atypes. of filling, .but has been found to be useful in some instances Where the filling has .tended to become frayed .as it has been drawn past the blade |9| According to the modification of Fig. 11a, a guide |96 having va. smaller notch i9?! expressly for the .purpose of ,preventing erratic travel o f the filling is provided. This notched guide may likewise keep the filling away from the cutter blade, but its main purpose is vto guide the n.11.- ing and prevent it from flying about .during the cutting cycle. Y

Now referring specifically .to Figs. 4 and .8, the means for operating the inner `clamp and cutter includes a cam |98 fixed .to a hub |88 whichis mounted on .the shaft 9 5 and retained in place and in a DI'Operly adjusted position by means of the nut 208. This cam will be described greater detail in av later paragraph. It functions upon followers 420| and 220.2 .mounted lat opposite sides of the general center line vof a -two armed lever comprising the arms 203 and 204 Divoted at 205 and connected .at its vlower forked end 206 by a suitable pin 207 .engageable within a notch or other indentation in van operating rod 208 slidable in Xbearings `in the casilla, one bearing 209 adjacent Vthefront part thereof and thesecond bearing 2m adjacent the opposite side of the casing.

This operating rod 20e carries at the end adjacent the .clamp and .cutter and .Outside the bearing 20s a depending `connector.eiellerxt ,2li having passed therethrough .a .projecting stud or pin v21,2 which .extends .through a slot 213 .in the casing extension orsupport .I 83 I:and into a cooperating aperture .in the cutter bar |90. Move, ments :of the operating rod 2.08 ,are .imparted thereby to .the cutter bar and fthus the .clamp may be .closedand the .cutter .operated to sever and to retain the severedend of vfilling running back to the supply, .or by other movements ,derived .from .the .cam .the .clamp :may .be ...opened Slightly .thereby to release the xheld lend, or V:the entire 4movable portion .of .the clamp ,and cublr extended rearwardly of .the 1001.11 ,a considerable distance .as illustrated Ain Fis. ,16, ,to explore and catch the filling preparatory to drawing it back toward the closed portion of the instrument for cutting.

A spring 2 I4 normally under considerable cornpression pushes the rod 228 in a direction to open the clamp and cutter while a second spring 2|5 enclosed within an extending housing 2|5 bolted or otherwise attached to the front face of the casing 52 serves to act as a buffer spring being compressed between the collar or shoulder 2|1 on a plunger 2|8 which in turn extends through to contact the reduced extending end of rod 208 carried within the bearing ZIB.

The cam |98 which controls the movements of the inner clamp and cutter is for the most part one which acts to impart movement in a single direction through the follower 22|, but which does act at one point in the cycle through the other follower 292, as a complementary cam for positively actuating the cutter. The main disk portion of the cam extending for 360 of arc is supplemented by a second part 2|9, Figs. 18 and 19, which is bolted to the main disk. rThe latter partial disk or sector is adjustable throughout an extent so as to vary the position of the point 22|) which determines the release of the held end during the insertion of the first pick and therefore the length of the first pick. Setting of this point is necessary to assure that the pick will extend clear across the fabric and beyond the extreme edge just far enough to serve in the production of a selvage.

The continued movement of the cams in the direction indicated by the arrow causes the follower 2l| to move into the depression between the points 22| and 222 at which time the cutter makes its extreme movement for the purpose of exploring the filling and catching it preparatory to terminating the length of the second pick by cutting, the position of the point 222 being adjusted by movement of the entire cam as the parts are originally assembled for establishing that particular point in the cycle. The spring 2|4 is under considerable compression and assists in moving the parts outwardly to their extreme position, but since there is considerable inertia and since the parts are to be moved with great speed, a short cam 223 bolted to a sector 224 likewise adjustable angularly about the main cam disk, serves to impart a positive movement at that time as it engages follower 202 and the pathways provided by cam 223 and that of the depression between the points 22| and 222 are substantially complementary. Sector 224 is also shaped to provide the cam point 22| and a concentric part in extension of the periphery f the main disk |98. Adjustment of the sector correspondingly moves point 22| and the point of cam 223. After the exploration for the filling and cutting and clamping thereof, the parts remain in closed position until the point 22|) is again reached at which time the cycle is repeated.

Now referring to Figs. 4, 13, 15, 16 and 17, a filling return guide mounted at the end of a supporting arm 225 comprises the arms 226 and 221 which converge to a V-shaped somewhat pointed thread controlling notch having a lowermost shelf or horizontal portion 228, the purpose of which is to restrain the filling so that it will align with the space between the nibs |45 and |46 at the injector. Fig. 17 shows the parts in that particular relationship at the termination of the second pick or start of the first pick since the injector and the position of the filling between the clamp and supply does not change during that interval.

At the start of the second pick the thread extends from the selvage and at the fell over the top of the cutter mechanism, but is still restrained wthin the notch or V portion and held upon the ledge or shelf 228 so that it is likewise properly disposed between the n ibs |45 and |46 before the injector moves outwardly and rotates for presenting that filling to the carrier.

This thread return guide has another function, namely, that of stripping the filling from the nibs as the injector is returned after the filling has been taken by the carrier. The movement of the injector back from presenting the thread to the carrier and the return rotation thereof wipes` the filling against either the upper or lower converging surface within the guide and that, in combination with the tension in the filling, results in a rapid stripping of the loop from the nibs |45 or |46, as the case may be.

For the first pick of a cycle the filling is desirably stripped or released from its nib as quickly as possible. The angle of the filling holding surfaces and action of the injector are combined with a wiping action of the edge of the lower arm 221 to accomplish that. At the second pick it is desired to hold the filling at the then acting nib as long as practicable, or at least, long enough to permit the cutter to enter between the tape and filling. For that purpose the outer surface of the nib |46, Fig. 15, is notched slightly to hold the thread until a safe point of release has been reached.

The lower arm of the guide extends forwardly to an enlarged end 229, Figs. 13 and 17, upon which is adjustably mounted a bearing block 230 formed from fibr-e or other wear-resistant, but more or less frictionless material against the top surface of which the tape 14 is guided or borne during reciprocating movement thereof. The block is adjustable being held in position by bolts 23| which pass through oversized openings in the end 229 of the arm or in some other way to permit a small amount of movement thereby to position the top surface of the block initially for proper operation of the parts, or to reposition it later in the event that becomes necessary or desirable.

In Fig. 12 one of the swords 64 is shown and brief mention has heretofore been made of that part and the general arrangement of elements operated thereby. The sword is of special form adapted to cooperate with the filling motion as the latter is positioned extremely close to the edge of the warp threads into which the filling is inserted, that being something not possible of obtainment with the usual sword employed on conventional looms or on other shuttleless looms heretofore known. Beginning just above the level of the top edge of the lay beam 62, the sword is curved rearwardly of the loom as at 232 and is then carried forwardly to a connecting pad 233 for the hand rail 63. 'I'his leaves between the hand rail and top of the lay a space 234 which is adapted to receive or permit the operation of the filling motion parts or thread handling instrumentalities such as the filling return guide and the inner clamp and cutter, especially when the latter extends forwardly for exploring the filling. Only the sword at the side at which the filling motion is positioned need be constructed in this manner, but, of course, if filling is inserted from both sides of the loom, both swords are correspondingly shaped.

.Operation v Now having described the details of a preferred embodiment of the invention as illnstrated .in the accompanying figures of the drawing, the epereten O f the mechanism will be reviewed.- mereV pertieular reference beine mede t .Fige- 13-17 Vand 26-39.

As shown in Fig. 2 6 which represents the posi,-Y tion of the various parts intimately involved in the introduction and insertion of filling, the partieuler position indeated there beine .termed the 0 pesitien for the eem Shaft et which time 1:he cycle `may be yconsidered to commence. The fill,- ing is at that point threaded through or conf trolled by the various devices including the outer clamp which is not closed at that time, the in,- jector, the lling return guide and the inner clamp which is closed and which holds the cut end of lling left at the termination of the Dre: vious pick or cycle. At that particular point, the injector has actually been vmoved inwardly slightly and has been rotated counterclockwise (as seen from the front of the loom). The care rler 8| is then withdrawn to lits outermost position.

Continued operation .of the loom causes that carrier to be projected inwardly toward the filling as the tape 14 is pushed inwardly by the tape actuating Vor driving means and, as illustrated in Fis. .27e the A5.0" position. the notch 8.3 has inet engaged the filling which at that time, as illusf trated in Fig. 13, is maintained in a, somewhat vertical direction by means of the injector pushed inwardly to its fullest extent and rotated to substantially a vertical position. The nib |45 holds a lOOp of the filling which extends from the inner clamp, about that nib and then up through the eyelet` |44 and back through the outer clamp to the supply.

Further movement of the parts as indicated in Fig. g8 .causes the filling to be drawn from the. supply -and extended in .the form of a. doubled. length of material since the cut end is still re.- tained by the inner clamp. This figure is taken at about'the 73 position at which time the filling and the carrier have actually entered the warp shed and also at which time the loop of filling held by nib |45, Fig. 13, has` been released. before explained, it is desirable on the first pick of a cycle to release the filling from thatlnib as quickly as is practicable, While some varia: tion lin the actual timing incidental. to V,that func.- tion is possible, the release must be accomplished fairly soon after the filling has been taken by the carrier to avoid possibility of the released loop .engaging undeereblv with .Some part o f the mechanism, lfor example, looping beneath the inner cutter rather than passing above as in-A tended.A If that Should happeny the piek Weud be measured longer than intended.

The alOn continues to the position of Fig. (2,9-, the 142 position Where the inner binder is opened. very .slightly thereby to release the .end of the. filling Snee et that time, .sufficient threes will here been measured t0 extend to the other Side 0f the fabric and to provide a proper amount thereof for forming a selvage as heretofore. ex?l pla-ined. It isV also apparent that the drawing of the filling from the supply is no longer necessary and in the following gure, Fig. 3o, about 3.` further advanced in the cycle, the outerl binder has closed to hold the yarn against further withdrawal from that source. The timing of parts at this critical point is such that the outer 16 binder does not hold the filling against withdrawal before it has been released by the inner binder. While about 3 of movement is one which serves satisfactorily, it is quite evident that some variation is possible.

It is to be borne in mind that the actual control of the elements being described at this point is derived from the various cams illustrated in Figs. 18-25 and that those cams are actually rotating at one-half the angular speed of the main cam shaft and therefore, will make a complete revolution for every two revolutions of the main cam shaft or a complete revolution for every two picks of filling inserted. The closing of the outer binder just above mentioned occurs due to the dropping of the'follower from the cam point |38, Fig. 20, that point being adjust: able to time the function properly. Likewise, the length of pick #l is also'governed by the dropping of the appropriate follower from point 2f|l on the cam illustrated in Fig. 18, that bringing about slight opening of the inner binder. Of course, the cams shown in Figs. 22-25 control the movements of the injector which incidentally has been returned practically to its innermost, horizontal, inactive position at 145 of cam shaft travel.

As shown in Fig. 31, the carrier 8| continues A on toward the center of the fabric where transf fer is effected as the .carrier 3.4 engages and traps the thread or filling pushed into the shed by the first carrier and draws it outwardly to the position shown in Fig. 32` The shed, of course, changes at an appropriate time just before or just about at the withdrawal of carrier 84 from the edge of the fabric and the pick is beaten into the fabric al1 in a manner understood by those familiar with this art. The carriers con,- tinue on outwardly returning toward their ini: tial position, Fig. 32 showing them at their 305 position at which the outer clamp has again opened so as to permit the drawing of lling from the supply when that becomes necessary.

.v At that time the filling is extending from the fell of the fabric and back to the supply being threaded through the eyelet in the injector and guided in the notch of the return guide, but not being particularly restrained by any other elementsY at that time. In Fig. 33., the 335 position, the tape driving means and the carriers are moving back to occupy practically the same position they did at the 0 position of Fig, 26.. The start of inserting the second pick` then commences shortly after the 345 position of Fig. 3.4. The carrier 8| then moves inwardly while the injector as controlled by the cams which govern it, is moving rearwardly and has engaged the filling between the nibs |615 and U56 and is just starting its rotation in a clockwise direction.

Now referring to Fig. 35, the 55 position at the,L second rotation of the mai-n drive or cam shaft, or the second pick of the cycle, the filling is being taken by the carrier, but it. is to be noted that at this time that. filling extends. from the fell, back over nib It, and down through eyelet |411 which has shifted to the position of Figs'.

14 and 15, that is, beneath .the carrier ratherv than above as in Fig. 13 or at'the taking of the first pick. The Elli-ng then extends from the eyelet back through. the: outery binder which is open, and to the supply.. Insertion of' the pick.

continues up to. approximately the position;

Fig. 36, at which time the inner cutter and" incidentally the inner movable clampl start to open 17 and to be moved rearwardly for exploring the filling which is at that time below the tape. lThe loop of filling extending from the carrier notch to the nib H56 is still retained by the nib being held in place by the small notch heretofore mentioned and shown in Figs. 14 and i5.

Continuation of the cycle to a position for the crank shaft oi about 110 or more continues at which time the loop may be released from that nib as the injector is withdrawn and also rotated slightly about its axis, the thread being stripped from the nib by the under side of the top arm 226 of the lling return guide. The 125o position is shown in Fig. 37 at which time the cutter and binder having explored and engaged the filling as illustrated in Fig. 15 are returning to their closed position, and also at which time the loop of material released from the nib idd has almost been drawn into the Salvage, that point being reached very shortly thereafter Iand before the 175 position of Fig. 38 at which time the cutter and the inner clamp have closed thereby severing and retaining the end of the filling extending from the supply. At that time the proper amount of material has been measured to reach clear across the fabric and continued movement of the parts results in transfer and extension of the filling to the other side of the fabric after which it is beaten in and the parts returned to their initial or Zero position as shown in Fig. 39, that position corresponding to the position of Fig. 26 at which point the cycle may again be repeated.

The movement of the cutter and inner clamp as just described is controlled by the cam illustrated in Figs. 18 and 19 and this description of operation as related to the diagrammatic ngures is also so tied up with the previous description of the mechanism itself that the operation of the various parts including the cams will be clear.

In Fig. 40 a small section of fabric has been illustrated and it can be seen there that the iilling is inserted in the form of hairpins or spaced pairs of picks interconnected by a selvage loop.

acterized by projecting selvage threads which may be interlocked by any form of selvage such, for example, as the well. known twisted selvage capable of being controlled by various mechanisms well known to those skilled in the art.

The example of operation just given relates to the settings peculiar to one particular form vthe invention may take. Of course, the values may well vary for other machines and change to an appreciable extent for the weaving of fabrics of different widths and for different speeds of operation.

The term reversed has been used to describe the effect produced upon the filling by the injector. The reversal or change in the relationship of the filling which is presented to and taken by the carrier is actually employed in sustaining a general -condition so that it remains constant. The reversal of a small stretch of filling thus results in establishing at each pick, a condition under which the released end of filling is always disposed or caused to be drawn at the same side of the inserting means (here the lower side of the carrier and its tape).

While one embodiment of the invention has ber of ways.

18 been disclosed, it is to be understood that the inventive concept may be carried out in a num- 'Ihe invention is, therefore, not to be limited to the precise details described, but is intended to embrace all variations and modincations thereof falling within the spirit of the invention and the scope of the claims.
